A bendable ultrasonic knife

Abstract

The invention provides a bendable ultrasonic knife, which includes a host, a transducer, a connecting rod driving cylinder, a connecting rod and a bending cutter head, the host is electrically connected to the transducer, and the connecting rod includes a first connecting rod and a second connecting rod. Two connecting rods, the output end of the transducer device is connected to the first rotating part, the side of the first rotating part away from the output end of the transducer device is connected to the first connecting rod, the host provides a stable ultrasonic frequency electrical signal, and the transducer device The ultrasonic frequency electric signal is converted into mechanical vibration, and the connecting rod transmits the mechanical vibration to the bending cutter head to realize the vibration cutting function of the bendable ultrasonic knife, while the bending cutter head, the first connecting rod and the second connecting rod The setting makes the bendable ultrasonic knife have higher operational flexibility, enabling doctors to cut the patient's lesion more accurately in minimally invasive laparoscopic surgery, which greatly increases the success rate of the operation.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bendable ultrasonic knife. Background technique [0002] Ultrasonic scalpel is a high-frequency electrosurgical device, mainly used for cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and quick postoperative recovery. It acts on human tissue to cut and coagulate, and will not cause side effects such as tissue dryness and burns. There is no current when the bent knife head works Through the human body, it is widely used in the operating room. It is known as the bloodless scalpel. The existing surgical resection mainly uses laparoscopic surgery. Due to the limitation of its own structure, the current ultrasonic scalpel cannot be bent due to its own structure. , When dealing with some special angles of cutting, such as the side and rear of the organs, doctors often cannot find a suitable angl...
